Cupidity \Cu*pid"i*ty\ (k?-p?d"?-t?), n. [F. cupidite, L.
   cupiditas, fr. cupidus longing, desiring, fr. cupere to long
   for, desire. See {Covet}.]
   1. A passionate desire; love. [Obs.]

   2. Eager or inordinate desire, especially for wealth; greed
      of gain; avarice; covetousness.

            With the feelings of political distrust were mingled
            those of cupidity and envy, as the Spaniard saw the
            fairest provinces of the south still in the hands of
            the accursed race of Ishmael.         --Prescott.
